I am about to build a new gaming rig. I'm getting a 27" IPS monitor for DisplayPort. My other 2 monitors will be 18.5" just for browsing/work purposes so the only monitor I will use for gaming will be the 27". Will I be able to run all 3 off a GTX 780 TI? I haven't built a gaming PC since the 8800 GTX was the latest and greatest (so it's been a minute)
